Ikhodi yombala ye-resistor

I-resistor iyisakhi esisesekethe sikagesi esilawula inani lamandla kagesi . Ama-resistor asetshenziswa kumasekethe kagesi ngokuvamile anesimo esiyindilinga kanye nentambo kuzo zombili izinhlangothi. Inani lokumelana le-resistor liboniswa ikhodi yombala futhi liboniswa ebusweni be-resistor.

Inani lokumelana le-resistor linganqunywa ngokuhumusha ikhodi yombala ye-resistor . Ukuze uqonde lokhu, qala uhlole ithebula elilandelayo, bese ufunda inkinga yesibonelo yokunquma inani lokumelana le-resistor.

Isibonelo sombuzo 1:
Inani lokumelana le-resistor esithombeni ohlangothini liyi...
Ingxoxo
Imibala emibili yokuqala imelela izinombolo ezimbili zokuqala zenani lokumelana, umbala wesithathu umelela amandla eshumi asetshenziselwa ukuphindaphinda kanti umbala wesine umelela ukubekezelelana kokuphambuka.
Umbala wokuqala = obomvu = 2
Umbala wesibili = i-orenji = 3
Umbala wesithathu = onsundu = 10¹ = 10
Umbala wesine = igolide = 5%

Inani lokumelana le-resistor lingu-230 Ω ngokuphambuka okungu-5% x 230 Ω = 11,5 Ω. Uma kukhona ushintsho ekushiseni, ukumelana okuncane kungu-230 Ω – 11,5 Ω = 218,5 Ω kanti ukumelana okuphezulu kungu-230 Ω + 11,5 Ω = 241,5 Ω

Isibonelo sombuzo 2:
Liyini inani lokumelana kwe-resistor esithombeni esiseceleni?
Ingxoxo
Umbala wokuqala = onsundu = 1
Umbala wesibili = omnyama = 0
Umbala wesithathu = okwesibhakabhaka = 10⁶ = 1000.000
Umbala wesine = igolide = 5%

Inani lokumelana le-resistor lingu-10.000.000 Ω ngokuphambuka okungu-5% x 10.000.000 Ω = 500.000 Ω. Uma kukhona ushintsho ekushiseni khona-ke ukumelana okuncane kungu-10.000.000 Ω – 500.000 Ω = 9.500.000 Ω kanti ukumelana okuphezulu kungu-10.000.000 Ω + 500.000 Ω = 10.500.000 Ω.
